.APPAZB'AJLUSl FOR VAPORIZING HYDROCARBON FUEL.

Application filed June 29,

This invention relates to apparatus for the prac-tice of the method of vaporizing fue described and claimed broadly in the copending application filed by the present applicant on April 21, '1922, Serial No. 555,845 in accordance with which it is proposed to separate out from the explosive mixture the heavy endsof liquid fuel, sub]ect such liquid fuel to a vaporizing heat at a point remote from the mixture and re-introduce such vaporized fuel back into the mixture for introduction at a predetermined temperature into an internal Acombustion motor. The present improvements relates particularly to the construction of the separator for effectivelyv withdrawing the unevaporated portion .of the fuel from the mixture during-its passage' to the inlet manifold. In accordance with the invention it is proposedA to break the inlet riser and so form and, dispos e thel open ends of the'broken section within a separator lchamber as to cause the mixture to take such a course as will best insure the 'collection of the unevaporated ends without impairing seriously the flow of the mixture.

This purpose is accomplished in the preferred form by sc forming the upper end of lthe lower section of the riser within the va. porizing chamber as to direct the employing mixture against the wall ofthe chamber where the unevaporated portions of fuel may collect over a large superficial area, and giv-A ing the lower end of the upper section of the riser such'a form as to receive the onilowing 85 mixture onlyA after it has described a very circuitous course which brings it over the v inner wall of the chamber to the greatest possible extent. The separator chamber coinmunicates with a vaporizing chamber ,for the 40 heavy fuel ends which is disposed at a point remote 'from the separator chamber and is subjected to the heat of the exhaust gases whereby the heav ends are evaporated' and returned 'to the mixture while the mixture it- '45 self is not subjected to the direct heat of such exhaust gases.

UTh'eevaporating chamber referred to, in

' accordance with t e improvements may also have disposed therein an electrical heating unit, the heat of which is suiicient to volatilize hydrocarbon'fuel collected therein, as for starting. i

The improvements will be described with 1923. VSerial No. 648,470.

Figure 4 is a view in transverse section through the separatorchamber shown in Figure 3 and taken on the pla-ne indicated by the line 4 4 of Figure 3 vand looking in the direction of the arrows.

' In accordance with the improved method in said copending application Serial No. 555,845 the mixture after being formedv'in fold anddevices are provided for separating out the unevaporated heavy liquid fuel ends. This unevaporated portion is then withdrawn tof an evaporating chamber located at a point remote from the 'mixture -where it is subjected to the hea-t of exhaust gases for complete volatilization and subsequent return in volatilized form ,to the onlowing mixture. The present devices are designed for the purpose of effectively withdrawing'the unevaporated liquid from the mixture, collecting it, transferring it to the l -any usual manner is passed to the vinlet mania, the inlet manifold at b, the exhaust pipe i at c, the`separator chamber within the inlet riser at d, and the vaporizing chamber at `c. The mixture formed by the metering devices arises through the pipe section f which terminates withinthe separator chamber d. Alongside of the riser section f but with its lowermost end disposed generally below the level of the upper end of said section f is asecond riser section g whichcommunicates with the Ainlet manifold 17C.v The general relationship between the sections f, g, in the preferred embodiment, is shown in Figure 4w where it appears that the upper edge g in the chamber e may be quickly evaporated.

ofthe section f is inclined as indicated at f and is so presented tothe side wall of the separator chamber d as to direct the mixture towards the side wallfand disperse it over a. large superficial area. the .lower edge of the other section g is inclined as indicated at g and turned away from the upper edge f of the section flso that the gaseous mixture within the chamber d before flowing into the section' g must circulate throughout the chamber d as indicated by the arrows in Figur-e 4. rlhis relationship insures the collecting of the liquid fuel particles carried in suspension in the mixture along the walls of the chamber Z and their constant separation out from'the gaseous lmixture which isfree to iiow without appreciable loss of pressure up through the section g to the inlet manifold b as a dry gas. The'bottom wall d of the chamber d is inclined as indicated-in Figure 3 and may be Jformed at opposite sides of the riser f withv drain channels (Z2 by which the liquid fuel which collects in the bottom is directed to the'evaporating `chamber at one side of the collecting chamber d and at a point relatively remote therefrom. The evaporating chamber e is preferably cast within the exhaust pipe c so that the heat to be exhausted will vbe applied directly thereto but will not be-communicated to the gaseous mixture flowing through the collecting chamber drained into the evaporating chamber -e/ in the manner described :will be completely volatilized by the exhaust gases and drawn back into` the chamber e where it. will commingle .with the gaseous mixture passing therethrough and'so enter the riser section g. Within the chamber c may be disposedl a supplementary heating unit )t which may, forconvenience, beef an electrical character by which, for starting, liquid collected withd. rThe liquid Lasarte for providing the motor with an initial rich starting charge.

The scope of the invention will appear from the `appended claims which. are intended to cover all equivalent forms ofthe.
